Well yeah that's the main struggle so I just went by who I think is most trouble in a war.
I legit think he might be lol. The way he used his instinctual skills against the Hi Shin Unit was quite impressive. I think there is nothing crazy with saying that as a general Gyou’Un of all people is equal to Keisha and Kochou.
Man was close to becoming a 3GH, that’s huge lol
Another example then, the inbetweeners are all worse generals than Keisha, Kochou, Akou and Kyou’En
Maybe Kansaro is close depending on his performance
Not yet. He will be one eventually but Riboku is constantly performing better than him imo. I can't put them on the same tier yet
And this is Gyou, a city that technically cannot be conquered with a normal siege. I don’t think we’ll ever get a feat as big as this one, all odds were against Qin taking Gyou whether its Riboku’s pre-established defenses for the region, numerical disadvantages, issues with food supply, SHK’s year long plan being rendered useless etc
What else do you require of Ousen lol, this is strategical genius at its best in the manga
